What is

Lead-in: Introduce the concept of

computational thinking (CT) and

stages of CT. Explain that CT will be

applied throughout this and other

units.

Small group/paired activity: Give

learners a scenario in which they are

asked to reverse-engineer a ‘clone’ of

a simple computer game (eg Space

Invaders or Tetris®). Learners must

identify the distinct steps of the

problem.

introduction.

Lead-in: Recap the concepts of

‘decomposition’, ‘pattern recognition’

and ‘pattern generalisation and

abstraction’ through Q&A session.

Explain that over the next two lessons

learners will explore the first stages of

algorithm design.

Small group or paired activity:

Using the same groups as previous

lessons, learners consider the

‘algorithms’ for different parts of the

game (eg controlling the ship, firing or

invader movement). Highlight that in

the early design stages of a software

solution the ‘algorithms’ only need to

be step-by-step instructions, using

everyday language, and do not need to

be presented in pseudocode or full

programming code.

Group activity (peer review and

feedback): At different stages during

the two lessons, ask groups to share

their work with other small groups.

Each group should give feedback about

the algorithms produced. Feedback

should focus on completeness and

accuracy.

Plenaries: Give groups different-

coloured pens to help them annotate

work when giving feedback, and so

they can annotate changes they have

made as a result of feedback.

Extension – independent learning

activity: If time and resources allow,

give learners a chance to implement

Tutor presentation: Introduce the

concept of pseudocode when designing

algorithms and planning computer

programs. Explain why pseudocode is

used as a planning and design tool (ie

to identify and plan the correct

sequence of tasks/processes for a

computer program). Introduce the

‘basic operations’ listed in the

specification. Explain that operations,

key commands and common

programming functions are typically

written in upper case within the

pseudocode. See the following video

Independent learning activity: Give

learners simple scenarios and flow

charts or components of a computer

program that they must present as

pseudocode. Focus on the basic

operations and avoid, if possible,

decisions and repetition. However,

depending on learners’ ability and their

programming experience, you may

decide to introduce concepts from later

lessons.

Note: try to introduce a different

scenario from previous lessons. It is

important that learners can apply

knowledge and demonstrate

understanding in a range of contexts.

They should be able to work from

Sequence-based scenarios could

include:

temperature conversion between

Fahrenheit and Celsius

calculating the area of a circle.

Plenary: Ask learners to

discuss/compare their solutions in

small groups. Ask one group to share

their solutions. As a class, discuss the

merits of each solution (try to identify

a group that has two varying but still

valid solutions). Highlight that,

depending on the scenarios, there may

be different ways of presenting

solutions which are still valid, just as

there are when creating a programmed

programs ‘decisions’ are often not

stand-alone and conditions are

regularly chained or combined with

repetition to reach an outcome.

the number. For each guess the

computer responds with higher or

local and global variables.

Tutor presentation: Introduce the

concept of local and global variables.

Explain how using them may affect the

way a program works and the data

within the program. Learners should

think of global variables as being used

by a number of different

functions/subroutines (passing values

Explain the purpose and use of the

functions and how they may be used

to add functionality to a program. At

this stage, just discuss and use these

functions at pseudocode level.

Learners will explore the syntax and

later. However, you may wish to give

examples of the functions working

the code, in order to give context.

a range of contexts in which learners

must apply understanding.

In particular these problems should

include the need to process using

discuss their solutions later. Each

group should deconstruct their

problem, and identify the different

‘functions’ that are required for the

solution and the ‘variables’ that are

needed. Identify the variables that

would be used by only one function

(local) and ones that may need to be

accessed by others (global). Extend

the task by asking learners to write a

function using pseudocode.

Learners should understand that

functions are used for two main

reasons - a) to break down a program

down so that it can be built by a team

of developers who each create one or

more functions that are they joined

together in the main program and b)

where code is identified as needing to

be reusable.

Problems could include:

a system to manage different

aspects of a house such as

switching lights on and off,

heating, cookers, closing

curtains etc.

way. A good example of this would be

to give learners a pseudocode where

an integer number is input by the user

several times in a program. Each time

the number is input it has to be

checked to confirm it is an integer

within a specific range. The range can

vary between inputs, but the process

of checking is exactly the same. So the

code to check the number is

repeatedly written into the program.

Learners should then create a function

that will pass in the number to be

checked, plus the upper and lower

limits and will pass back a Boolean

value of true or false (is valid or is not

valid). This means coding the

validation routine just once and

reusing as often as necessary.

learners’ work and consider their

solutions.

Plenary: Further to discussion, allow

learners to revisit solutions and refine

their work.

similarities and differences between,

the two data structures.
